Topical foam vehicle delivery systems are relatively new to dermatology, yet they already have established an important role in patient care. While foam vehicles have already undergone several formulation enhancements, additional advancements are anticipated. Next generation emollient foams are especially useful for inflammatory skin conditions associated with an impaired epidermal barrier.
Despite the relatively higher costs associated with the development and manufacture of these specialized formulations, data suggest that foams may not in actual use cost more than other formulation types. The high level of patient satisfaction and ease of application associated with topical foams will likely drive continued development in both the prescription and non-prescription skin care realms.
